Description

Technical Field

[0001] This invention belongs to the field of visual inspection technology, and more specifically, relates to a visual inspection device for surface defects of glass insulators. Background Technology

[0002] To ensure product quality and long-term operational reliability, transparent glass insulators must undergo rigorous visual defect inspection before leaving the factory. This inspection aims to detect any defects that may exist on their surface or inside, such as bubbles, cracks, impurities, scratches, or irregular shapes. These minor defects can not only degrade the mechanical strength of the insulator but may also become the starting point for breakdown under high-voltage electric fields, ultimately leading to the failure of the entire power line. Therefore, comprehensive and accurate visual quality control is an indispensable and crucial link in the production process.

[0003] However, when using visual inspection equipment to perform automated appearance inspection of transparent glass insulators, the transparency of the material itself becomes a major obstacle to improving accuracy. When light passes through the glass medium, complex refraction, reflection, and transmission phenomena occur, causing the images captured by the equipment to be superimposed and interfered with by the inner and outer surface features of the insulator and the background environment, thus significantly reducing the signal-to-noise ratio of the image. This optical interference can mask real surface defects and may also produce false defect images, seriously affecting the accuracy and reliability of visual inspection equipment in defect identification and judgment. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a visual inspection device for surface defects of glass insulators that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] A visual inspection device for surface defects of glass insulators includes a frame and an inspection platform disposed on the frame. The inspection platform has a perforation, and the upper end of the perforation has an annular placement groove. An inspection head with a supplementary light is connected to the frame and located above the inspection platform. A lowering and lifting device is fixedly installed on the frame, and a frame is fixedly connected to the lowering and lifting device. A device platform is rotatably mounted on the frame via a rotating rod. Two symmetrically arranged inner liners are installed on the device platform. The frame has an interchange part for driving the device platform to flip up and down. A liquid storage tank located below the inner liners is fixedly connected to the frame.

[0007] Preferably, the switching part includes a driven gear rotatably mounted on the outer wall of the frame, a first rack is fixedly mounted on the frame, the driven gear is connected to the rotating rod through a first worm gear assembly, the worm in the first worm gear assembly is connected to the rotating shaft of the driven gear through a one-way bearing, and the driven gear will slide over the first rack before the bottom liner enters the liquid storage tank.

[0008] Preferably, a support column is rotatably connected to the device platform, and the two inner linings are respectively fixedly connected to the two ends of the support column. The device platform has a cavity inside and a swinging part that drives the support column to reciprocate.

[0009] Preferably, the swinging part includes a horizontal shaft rotatably connected to the device platform. The horizontal shaft is connected to the support column through a second worm gear assembly. Both ends of the horizontal shaft are fixedly installed with driven gears. A second rack is fixedly installed on the frame. The teeth on the second rack are multiple segments arranged at equal intervals. When the inner liner at the top gradually approaches the insulator, the driven gear will slide across the second rack. A torsion spring is installed between the driven gear and the outer wall of the device platform.

[0010] Preferably, an upward lifting device is fixedly installed on the frame, and a device cover is fixedly connected to the telescopic end of the upward lifting device. A turntable is rotatably installed at the bottom of the device cover, and the supplementary light and the detection head are both installed at the bottom of the turntable. A rotating part for driving the turntable to rotate is provided inside the device cover.

[0011] Preferably, the rotating part includes a first motor fixedly installed inside the device cover, and the output shaft of the first motor is connected to the turntable through two meshing first transmission gears.

[0012] Furthermore, the bottom of the turntable is provided with multiple circumferentially distributed top rods, and rollers are rotatably mounted on the lower ends of the top rods.

[0013] Furthermore, the bottom of the turntable is provided with multiple circumferentially distributed vertical grooves, and multiple top rods are slidably installed in the multiple vertical grooves respectively, and a top pressure spring is installed between the top rod and the inner top of the vertical groove.

[0014] Furthermore, the testing platform is disc-shaped, and the perforations and placement slots on the testing platform are provided in multiple sets distributed around the circumference. A column is fixedly connected to the frame, and the testing platform is rotatably mounted on the column. A second motor is fixedly mounted on the column, and the output shaft of the second motor is connected to the testing platform through two meshing second transmission gears.

[0015] Furthermore, the lining is arched upwards in the middle and is elastic.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0017] 1. By placing the inner lining within the concave surface at the lower end of the insulator, the light from the supplementary lamp can be blocked and reflected by the inner lining. The light does not pass directly through the transparent insulator, thus making the defects of the insulator more obvious and improving the accuracy of surface defect detection of the insulator.

[0018] 2. The present invention uses the elastic force of the top pressure spring to make the roller elastically press against the surface of the insulator, thereby making the insulator and the concave surface of the inner lining more tightly, thus reducing the impact of the gap between the two on the detection of appearance defects.

[0019] 3. The present invention uses a first motor to drive a turntable to rotate, which in turn drives the supplementary light, the detection head and the roller to sweep in a circular path above the insulator, thereby enabling a more comprehensive inspection of the appearance defects of the insulator.

[0020] 4. By immersing the liner in the coupling liquid, the gap between the liner and the concave surface of the insulator is filled by the coupling liquid, making the gap smaller and even reaching a state of no gap. This can further improve the visual detection accuracy of surface defects of the insulator. The liner is rotated each time, which keeps its surface moist and also cleans the surface of the liner, reducing the impact of impurities on the insulator surface on the liner.

[0021] 5. Through the cooperation of the first rack and the driven gear, the support column will drive the inner liner at both ends to rotate intermittently in both directions. The bottom inner liner will shake off excess coupling fluid from its surface, preventing excess coupling fluid from affecting the seal between the two and saving coupling fluid. The top inner liner can fit more efficiently and tightly into the concave surface of the insulator and can discharge some of the air bubbles generated between the two, further improving the subsequent visual inspection effect.

[0022] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] Example 1: Refer to Figures 1-8A visual inspection device for surface defects of glass insulators includes a frame 1 supporting the entire device, and an inspection platform 12 mounted on the frame 1. The inspection platform 12 has a through hole 13, the diameter of which is smaller than the outer diameter of the insulator but larger than the inner diameter of the concave surface at the lower end of the insulator. An annular placement groove 14 is provided at the upper end of the through hole 13 for placing the insulator. An inspection head 6 with a supplementary light 7 is connected to the frame 1 and located above the inspection platform 12. The inspection head 6 is a camera of the visual inspection device, such as an industrial camera. A lowering and lifting device 16, which is an electric telescopic rod or a cylinder, is fixedly mounted on the frame 1. A frame 15 is fixedly connected to the lowering device 16. A device platform 18 is rotatably mounted on the frame 15 via a rotating rod 17. Two symmetrically arranged inner liners 20 are installed on the device platform 18. The inner liners 20 are located below the detection platform 12. The surface flatness of the inner liners 20 is greater than or equal to that of the insulator, and the surface can be blackened as needed. The frame 15 is provided with an adjustment part that drives the device platform 18 to flip up and down. A liquid storage tank 29 located below the inner liners 20 is fixedly connected to the frame 1. The liquid storage tank 29 is used to store coupling fluid. The coupling fluid can be deionized water or distilled water that can reduce bubbles. It needs to be circulated and filtered by the equipment during use to keep the coupling fluid clean.

[0035] Specifically, in use, the insulator is placed concave-side down in the placement groove 14. The edge of the insulator is then confined within the groove. The lowering and lifting device 16 lifts the frame 15 upwards, which in turn lifts the two inner liners 20 simultaneously. The uppermost inner liner 20 passes through the perforation 13 and gradually fits into the lower concave surface of the insulator. The detection head 6 can then detect and capture any defects in the insulator's appearance. During the detection process, because the inner liners 20 are positioned within the lower concave surface of the insulator, the light from the supplementary light 7 is blocked and reflected, preventing the light from passing directly through. The transparent insulator makes defects more visible, thus improving the accuracy of surface defect detection. After the inner liner 20 is wetted by the coupling fluid, the gap between the inner liner 20 and the concave surface of the insulator is filled by the coupling fluid, making the gap even smaller, or even reaching a gapless state. This further improves the visual detection accuracy of surface defects of the insulator. The swapping unit can realize the cyclic swapping of the two inner liners 20. Each swap keeps the surface of the inner liner 20 moist and cleans the surface of the inner liner 20, reducing the impact of impurities on the insulator surface on the inner liner 20.

[0036] The inner liner 20 is arched upward in the middle and is elastic. As the inner liner 20 gradually fills the concave surface of the insulator, the middle part of the inner liner 20 will first adhere tightly to the inner wall of the insulator, and then the periphery of the inner liner 20 will gradually adhere to the inner wall of the insulator. This can effectively reduce the generation of air bubbles between the two, and even if air bubbles are generated, they can be automatically discharged.

[0037] Example 2: Refer to Figures 1-4 as well as Figures 6-7 A visual inspection device for surface defects of glass insulators, which is basically the same as that in Example 1, but further includes the following:

[0038] The aforementioned switching part includes a driven gear 22 rotatably mounted on the outer wall of the frame 15, a first rack 23 fixedly mounted on the frame 1, the driven gear 22 and the rotating rod 17 are connected by a first worm gear assembly 21, the worm in the first worm gear assembly 21 is connected to the rotating shaft of the driven gear 22 through a one-way bearing, and the driven gear 22 will pass over the first rack 23 before the bottom liner 20 enters the liquid storage tank 29.

[0039] Specifically, after the test is completed, the frame 15 and the inner liner 20 are driven to reset downwards by the lower lifting device 16. Before the lower inner liner 20 enters the liquid storage tank 29, the driven gear 22 will sweep across the first rack 23. The driven gear 22 will then drive the rotating rod 17 to rotate through the first worm gear assembly 21. The rotating rod 17 will drive the device platform 18 to flip up and down, thus causing the two inner liners 20 to be swapped. The frame 15, which continues to move downwards, will cause the swapped lower inner liner 20 to be immersed in the coupling liquid in the liquid storage tank 29. When the frame 15 moves upwards, the driven gear 22 will sweep across the first rack 23 again. Since the worm in the first worm gear assembly 21 is connected to the shaft of the driven gear 22 through a one-way bearing, the driven gear 22 will only rotate in the opposite direction instead of driving the worm to reverse.

[0040] Example 3: Reference Figure 4 as well as Figures 6-8 A visual inspection device for surface defects of glass insulators, which is basically the same as that in Example 2, but further includes the following:

[0041] A support column 19 is rotatably connected to the aforementioned device platform 18. Two inner liners 20 are respectively fixedly connected to the two ends of the support column 19. The device platform 18 has a cavity inside. The device platform 18 is provided with a swinging part that drives the support column 19 to reciprocate. The swinging part includes a horizontal shaft 24 rotatably connected to the device platform 18. The horizontal shaft 24 is connected to the support column 19 through a second worm gear assembly 25. Both ends of the horizontal shaft 24 are fixedly installed with driven gears 28. A second rack 27 is fixedly installed on the frame 1. The teeth on the second rack 27 are multiple segments with equal spacing. When the top inner liner 20 gradually approaches the insulator, the driven gear 28 will slide across the second rack 27. A torsion spring is installed between the driven gear 28 and the outer wall of the device platform 18.

[0042] Specifically, as the inner liner 20 gradually approaches the insulator, and after the first rack 23 ceases to mesh with the driven gear 22, the upward-moving frame 15 drives the driven gear 28 to sweep across the second rack 27 with multiple tooth segments. The driven gear 28 then rotates intermittently. Since a torsion spring is installed between the driven gear 28 and the device platform 18, the driven gear 28 will intermittently rotate forward and backward under the action of the second rack 27 and the torsion spring, thereby driving the horizontal shaft 24 to intermittently rotate forward and backward. The horizontal shaft 24 will drive the support column 19 to intermittently rotate forward and backward through the second worm gear assembly 25. The support column 19 will then drive the inner liners 20 at both ends to intermittently rotate forward and backward. The bottom inner liner 20 will shake off excess coupling fluid from its surface, preventing excess coupling fluid from affecting the seal between the two and saving coupling fluid. The top inner liner 20 can fit more efficiently and tightly into the concave surface of the insulator and can expel some of the air bubbles generated between them, further improving the subsequent visual inspection effect.

[0043] Example 4: Reference Figure 2 , Figure 3 , Figure 5 as well as Figure 6 A visual inspection device for surface defects of glass insulators, which is basically the same as that in Example 3, but further includes the following:

[0044] A lifting device 26 is fixedly installed on the frame 1. The lifting device 26 is an electric telescopic rod or a cylinder. The telescopic end of the lifting device 26 is fixedly connected to a device cover 2. A turntable 3 is rotatably installed at the bottom of the device cover 2. The supplementary light 7 and the detection head 6 are both installed at the bottom of the turntable 3. The supplementary light 7 and the detection head 6 are provided in at least two sets arranged in a circle. The device cover 2 is provided with a rotating part that drives the turntable 3 to rotate. The rotating part includes a first motor 4 fixedly installed inside the device cover 2. The output shaft of the first motor 4 is connected to the turntable 3 through two meshing first transmission gears 5.

[0045] Specifically, during inspection, the lifting device 26 moves the device cover 2 downwards, which in turn moves the supplementary light 7 and the inspection head 6 at the bottom closer to the upper surface of the insulator. At this time, the inspection head 6 can complete the detection of appearance defects of the insulator. Then, the first motor 4 is started, which drives the turntable 3 to rotate through two meshing first transmission gears 5. The turntable 3 can drive the supplementary light 7, the inspection head 6 and the roller 11 to sweep in a circular path above the insulator, so as to more comprehensively detect appearance defects of the insulator.

[0046] The bottom of the turntable 3 is provided with multiple circumferentially distributed top rods 9, and rollers 11 are rotatably installed at the lower end of the top rods 9. The bottom of the turntable 3 is provided with multiple circumferentially distributed vertical grooves 8. The multiple top rods 9 are slidably installed in the multiple vertical grooves 8 respectively, and a top pressure spring 10 is installed between the top rods 9 and the inner top of the vertical grooves 8.

[0047] Specifically, when the device cover 2 moves downwards towards the insulator, multiple circumferentially distributed rollers 11 will press against the surface of the insulator. At this time, the elastic force of the top pressure spring 10 will cause the rollers 11 to press against the surface of the insulator, thus making the insulator and the concave surface of the inner liner 20 more tightly, thereby reducing the impact of the gap between the two on the detection of appearance defects. In practice, in order to achieve better results, the insulator can be lifted upwards from the placement groove 14 and suspended in the air by using the lower lifting device 16 to drive the inner liner 20.

[0048] Example 5: Refer to Figures 1-3 A visual inspection device for surface defects of glass insulators, which is basically the same as that in Example 4, but further includes the following:

[0049] The aforementioned testing platform 12 is disc-shaped, and the perforations 13 and placement slots 14 on the testing platform 12 are provided with multiple sets of circumferentially distributed holes. A column 30 is fixedly connected to the frame 1, and the testing platform 12 is rotatably mounted on the column 30. A second motor 31 is fixedly mounted on the column 30, and the output shaft of the second motor 31 is connected to the testing platform 12 through two meshing second transmission gears 32.

[0050] Specifically, during use, one of the perforations 13 is aligned vertically with the detection head 6. During the detection process, the insulator to be detected can be placed in the empty placement slot 14, and then the insulator that has been detected can be taken out from the placement slot 14. After the detection is completed, the second motor 31 is started. The second motor 31 can drive the detection table 12 to rotate through two meshing second transmission gears 32, which can conveniently complete the position change of the insulator and facilitate the precise loading and unloading of the insulator.

[0051] In use, the insulator is placed concave-side down in the placement groove 14, confining the edge of the insulator within the groove. Then, the lowering device 16 lifts the frame 15 upwards, causing the two inner liners 20 to rise simultaneously. The uppermost inner liner 20 passes through the perforation 13 and gradually fits into the lower concave surface of the insulator. Simultaneously, the uppering device 26 moves the device cover 2 downwards, bringing the supplementary light 7 and the detection head 6 closer to the upper surface of the insulator. The detection head 6 then detects and captures surface defects in the insulator. During detection, because the inner liners 20 are obscured within the lower concave surface of the insulator, the light from the supplementary light 7 is blocked and reflected, preventing direct penetration of the transparent insulator. This makes the defects more apparent, thus improving the accuracy of surface defect detection.

[0052] After the test is completed, the lowering device 16 drives the frame 15 and the inner liner 20 to reset downwards. Before the lower inner liner 20 enters the liquid storage tank 29, the driven gear 22 sweeps across the first rack 23. The driven gear 22 then drives the rotating rod 17 to rotate through the first worm gear assembly 21. The rotating rod 17 drives the device platform 18 to rotate up and down, thus causing the two inner liners 20 to be swapped. The frame 15, which continues to move downwards, will cause the swapped lower inner liner 20 to be immersed in the coupling liquid in the liquid storage tank 29. When the frame 15 moves upwards, the driven gear 22 sweeps across the first rack 23 again. The worm in the first worm gear assembly 21 is connected to the shaft of the driven gear 22 via a one-way bearing. Thus, the driven gear 22 will only rotate in the opposite direction instead of driving the worm to rotate in the opposite direction. After the inner liner 20 is wetted by the coupling fluid, the gap between the inner liner 20 and the concave surface of the insulator will be filled by the coupling fluid, and the gap between the two will be smaller, or even reach a state of no gap. This can further improve the visual inspection accuracy of surface defects of the insulator. The inner liner 20, which is rotated up and down each time, can keep its surface moist and clean its surface, reducing the impact of impurities on the surface of the insulator on the inner liner 20.

[0053] As the inner liner 20 gradually approaches the insulator, and after the first rack 23 ceases to mesh with the driven gear 22, the upward-moving frame 15 drives the driven gear 28 to sweep across the second rack 27 with multiple tooth segments. The driven gear 28 then rotates intermittently. Since a torsion spring is installed between the driven gear 28 and the device platform 18, the driven gear 28 will intermittently rotate forward and backward under the action of the second rack 27 and the torsion spring, thus driving the horizontal shaft 24 to intermittently rotate forward and backward. The horizontal shaft 24 will drive the support column 19 to intermittently rotate forward and backward through the second worm gear assembly 25. The support column 19 will then drive the inner liners 20 at both ends to intermittently rotate forward and backward. The bottom inner liner 20 will shake off excess coupling fluid from its surface, preventing excess coupling fluid from affecting the seal between the two and saving coupling fluid. The top inner liner 20 can fit more efficiently and tightly into the concave surface of the insulator and can expel some of the air bubbles generated between them, further improving the subsequent visual inspection effect.
